Description

Adjustable mount and child safety seat

Technical Field

The present application relates to an adjustable mounting seat and a child safety seat comprising the adjustable mounting seat.

Background Art

A child safety seat is a device designed specifically for children. Children are restrained in the safety seat while riding in a car. In the event of a car collision or sudden deceleration, the impact pressure on the children is reduced and the children's body movement is restricted, thereby reducing injuries to them and effectively improving the safety of children riding in a car.

In order to more effectively improve the safety of child safety seats and prevent them from tipping over, it is necessary to adjust the degree of contact between the child safety seat and the car seat backrest. In the prior art, this is mostly done indirectly by adjusting the length of ISOFIX. However, such an adjustment range is very ineffective and cannot meet the needs of practical use.

In addition, a child safety seat and its adjustment mechanism include a push rod clamping block, a locking piece and a driving piece; the push rod clamping block is slidably arranged on the base along a first direction and is detachably engaged with the push rod; the locking piece is slidably arranged on the base along a second direction and is detachably engaged with the push rod clamping block; the driving piece is slidably arranged on the base along the second direction and is connected to the push rod clamping block; when the locking piece is disengaged from the push rod clamping block, the driving piece can drive the push rod clamping block to slide in the first direction to disengage from the push rod, thereby adjusting the angle of the push rod to make the push rod and the car seat back fit better, and can adjust the leg placement space of infants and young children to make the infants and young children sit more comfortably.

In the above child safety seat, although the angle of the push rod can be adjusted, there are still the following problems. First, the adjustment mechanism is complicated, involving the connection and coordination of components in at least two directions, so it is difficult to manufacture and assemble, and the cost is high. In addition, the adjustment operation is complicated, and it is necessary to take into account the coordination of multiple components and to operate in multiple directions, so it is easy to cause operational failures, and there are hidden dangers in safety and reliability.

Therefore, the existing technologies all have the problem that the degree of fit between the child safety seat and the car seat back cannot be adjusted in an efficient and simple manner.

The accompanying drawings and example embodiments described below are not meant to limit the scope of the present embodiment to a single embodiment. Its embodiments can be realized by making some or all of the described or illustrated elements interchangeable. In addition, in the case where some elements of the disclosed exemplary embodiments can be implemented partially or entirely using known components, in some cases, only those parts of such known components necessary for understanding the present embodiment are described, and detailed descriptions of other parts of these known components are omitted to avoid blurring the present embodiment.

The following detailed description takes the application of the adjustable mounting seat 10 according to the present application to a child safety seat 20 as an example, and the adjustable mounting seat 10 may also be applied to other occasions.

The following will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1 , this figure is a schematic diagram of an adjustable mounting seat 10 according to the present application being installed on a child safety seat 20. The child safety seat 20 can be installed on a car seat facing forward or backward. The following description takes the child safety seat 20 being installed on a car seat facing backward as an example, that is, the occupant of the child safety seat faces the rear of the car.

The child safety seat 20 is arranged on the base 16 of the adjustable mounting seat 10, and then the child safety seat 20 is fixedly connected to the car seat by the adjustable mounting seat 10, for example, it can be fixed by the ISOFIX interface and/or LATCH interface on the car. In order to improve the safety of the child safety seat 20 and prevent the child safety seat from overturning, the child safety seat 20 can be closely fitted to the backrest of the car seat by the adjustable mounting seat 10. To this end, as shown in FIG. 1, the top rod 12 of the adjustable mounting seat 10 is pressed against the child safety seat 20, and the degree of fit between the child safety seat 20 and the backrest of the car seat can be changed by adjusting the angle of the top rod 12.

Please refer to FIG. 2 for details, which is a schematic diagram of the structure of the adjustable mounting seat 10 according to the present application. The adjustable mounting seat 10 includes the mandrel 12, the tail frame 14, the base 16 and the mandrel adjustment mechanism 18 as described above. The mandrel 12 and the tail frame 14 are arranged opposite to each other and both extend upward from the base 16, so that a space is formed by the mandrel 12, the tail frame 14 and the base 16, and the child safety seat 20 is accommodated in the space. Preferably, the tail frame 14 and the base 16 can be integrally formed. The angle of the mandrel 12 relative to the base 16 can be adjusted by the mandrel adjustment mechanism 18, and then the distance S between the mandrel 12 and the tail frame 14 can be adjusted.

The structure of the push rod adjustment mechanism 18 will be described in detail below with reference to FIG. 3 and FIG. 4 , wherein FIG. 3 is a schematic diagram of the structure of the push rod adjustment mechanism 18 of the adjustable mounting seat 10 according to the present application; and FIG. 4 is a schematic diagram showing in detail the structure of the push rod adjustment mechanism 18 of the adjustable mounting seat 10 according to the present application. The base 16 is provided with a base bracket 161, and the push rod 12 is pivotally connected to the base bracket 161 through a push rod pivot shaft 121, so that the push rod 12 can adjust the angle θ of the push rod 12 relative to the base bracket 161 by pivoting around the push rod pivot shaft 121, and thus the distance S between the push rod 12 and the tail frame 14 can be adjusted.

According to the present application, the pivot angle of the push rod 12 is 22°, and the adjustment range of the angle θ of the push rod 12 relative to the base bracket 161 is 119° to 141°. In this way, the push rod 12 can be close to the backrest of the rear seat of the car, preventing the child safety seat 20 from tipping over to the backrest of the rear seat during a collision, thereby improving the safety of the child safety seat 20. In addition, the pivot angle of the push rod 12 is 22°, and the various angles make the child safety seat 20 more diverse in terms of storage space and installation methods, making the child safety seat 20 more convenient to store and install.

The adjustment of the angle θ between the push rod 12 and the base bracket 161 is completed by the push rod adjustment mechanism 18. The push rod adjustment mechanism 18 is arranged between the push rod 12 and the base bracket 161. One end of the push rod adjustment mechanism 18 can be engaged with and locked to the base bracket 161 and unlocked from the base bracket 161, and the other end of the push rod adjustment mechanism 18 can be fixedly connected to the push rod 12, so that the push rod adjustment mechanism 18 can be used to adjust the angle θ between the push rod 12 and the base bracket 161.

Specifically, the push rod adjustment mechanism 18 includes an operating member 181, a positioning member 182 and an elastic member 183. In addition to the pivot connection between the push rod 12 and the base bracket 161, the positioning member 182 and the base bracket 161 are also engaged with each other through the positioning mechanism to position, and can also be positioned again at multiple different positions after the push rod 12 is rotated at different angles relative to the base bracket 161. According to one embodiment of the present application, as shown in Figures 3 and 4, the positioning mechanism includes a first positioning tooth 1611 provided on the base bracket 161 and a second positioning tooth 18211 provided on the positioning member 182, and the second positioning tooth 18211 can be engaged with the first positioning tooth 1611, thereby locking the angle θ of the push rod 12 relative to the base bracket 161. The first positioning tooth 1611 and the second positioning tooth 18211 are respectively arranged along the end surfaces facing the base bracket 161 and the positioning member 182, so that after the top rod 12 is pivoted to a certain angle relative to the base bracket 161, the first positioning tooth 1611 and the second positioning tooth 18211 can still engage with each other, thereby allowing the top rod 12 to still be positioned and engaged relative to the base bracket 161 after changing the angle θ relative to the base bracket 161.

According to another embodiment of the present application, the positioning mechanism is composed of a plurality of grooves provided on the base bracket 161 and a plurality of protrusions provided on the positioning member 182. The top rod 12 and the base bracket 161 are positioned by engaging the corresponding grooves and protrusions. After the top rod 12 pivots a certain angle relative to the base bracket 161, another corresponding protrusion and groove can still engage with each other, so that the top rod 12 can still be positioned relative to the base bracket 161 after the angle relative to the base bracket 161 is changed. Of course, the positioning mechanism can also be composed of a plurality of protrusions provided on the base bracket 161 and a plurality of grooves provided on the positioning member 182. The number and spacing of the grooves and the corresponding protrusions can be set according to the range of the pivot angle of the top rod 12 relative to the base bracket 161 and the angle setting of each rotation.

If the above-mentioned method of engaging the first positioning tooth 1611 and the second positioning tooth 18211 is used to position the push rod 12 and the base bracket 161, then after unlocking and positioning, the push rod 12 can be rotated to any angle within a certain range relative to the base bracket 161 to achieve re-engagement and positioning; and if the method of engaging the groove and the protrusion to position the push rod 12 and the base bracket 161 is used, then after unlocking and positioning, the angle at which the push rod 12 pivots relative to the base bracket 161 needs to be set based on the distance between the matching protrusions or grooves, that is, it must be pivoted to a specific angle before re-engagement and positioning can be achieved. Therefore, different positioning mechanisms can be selected according to specific practical needs.

The specific structure of each component of the push rod adjustment mechanism 18 and the specific matching relationship between the push rod adjustment mechanism 18 and the base 16 are described in detail below with reference to FIG. 5 , wherein FIG. 5 is an exploded schematic diagram showing in detail the structure of the base 16 and the push rod adjustment mechanism according to the present application. The operating member 181 can be in the form of a sleeve, and the push rod 12 is pivotally connected to the base bracket 161 through the push rod pivot shaft 121 after being inserted into the operating member 181. The positioning member 182 includes a coupling portion 1821 and a fixed seat 1822. In the embodiment shown in FIG. 5 , the positioning member 182 includes two fixed seats 1822, which are symmetrically buckled and fixed on the push rod 12, and the coupling portion 1821 is slidably arranged between the two fixed seats 1822, and the coupling portion 1821 can be engaged and positioned with the base bracket 161, and can also be disengaged from the engagement with the base bracket 161. The end of the joint portion 1821 that is engaged with the base bracket 161 is provided with the second positioning tooth 18211 as described above, and the second positioning tooth 18211 cooperates with the first positioning tooth 1611 on the base bracket 161. The operating member 181 is sleeved on the outer periphery of the top rod 12, covering at least a portion of the top rod 12 and the two fixing seats 1822, and the operating member 181 is connected to the joint portion 1821, so that the joint portion 1821 can be pulled by pulling the operating member 181, so that the second positioning tooth 18211 of the joint portion 1821 is disengaged from the cooperation with the first positioning tooth 1611 on the base bracket 161.

An elastic member 183 is disposed between the positioning member 182 and the push rod 12. For example, a groove 18221 is disposed on one of the fixing seats 1822 to accommodate the elastic member 183, and a window 18212 is disposed at a position corresponding to the joint portion 1821. The elastic member 183 accommodated in the groove 18221 is partially exposed from the window 18212. Thus, when the joint portion 1821 slides outwardly along the push rod 12 in a direction away from the base bracket 161, the edge of the window 18212 of the joint portion 1821 compresses the elastic member 183 accommodated in the groove 18221. Thus, when the operating member 181 is released, the compressed elastic member 183 provides a restoring force to pull the joint portion 1821 toward the base bracket 161, so that the second positioning tooth 18211 is engaged and positioned with the first positioning tooth 1611, thereby engaging and positioning the push rod 12 relative to the base bracket 161.

The operating member 181 of the top rod operating mechanism 18 is connected to the engaging portion 1821, so that the engaging portion 1821 can be operated by pulling the operating member 181, so that the engaging portion 1821 can slide along the top rod 12. In one embodiment according to the present application, as shown in FIG. 4 , the operating member 181 is provided with an operating member hole 1811, the positioning member 182 together with the top rod 12 passing therethrough is accommodated in the operating member hole 1811, and the operating member 181 and the engaging portion 1821 are connected to each other, for example, by a pin or the like. According to this embodiment, when the operating member 181 is pulled in an outward direction along the top rod 12 away from the base bracket 16, the operating member 181 and the coupling portion 1821 slide together along the top rod 12 in a direction away from the base bracket 16. The elastic member 183 is compressed at this time, and the second positioning tooth 18211 on the coupling portion 1821 disengages from the first positioning tooth 1611 on the base bracket 161. At this time, the top rod 12 can be pivoted relative to the base bracket 161. After adjusting the rear pivot angle, the operating member 181 is released. The compressed elastic member 183 provides a restoring force to push the positioning member 182 to slide in a direction toward the base bracket 161, and the second positioning tooth 18211 on the coupling portion 1821 is engaged with the first positioning tooth 1611 on the base bracket 161 again, locking the top rod 12 and the base bracket 161.

According to another embodiment of the present application, the positioning member 182 can also be set to move in a direction perpendicular to the illustrated paper to disengage the lock. In this case, the elastic member 183 needs to be set between the positioning member 182 and the top rod 12 along the direction of movement of the positioning member 182, and the operating member 181 can be set on the side of the top rod 12. According to this embodiment, the operating member 181 is directly pressed, and the operating member 181 pushes the positioning member 182 to disengage the engagement with the base bracket 161 to release the lock. After adjusting in place, the operating member 181 is released, and under the restoring force of the elastic member 183, the positioning member 182 locks the top rod 12 and the base bracket 161 again.

In the above-mentioned embodiments according to the present application, as shown in FIG. 1, FIG. 2, FIG. 5, etc., two push rod adjustment mechanisms 18 are provided corresponding to the base bracket 161 of the base 16, and the two push rod adjustment mechanisms 18 both have the specific structure as described above. Therefore, when it is necessary to adjust the angle θ of the push rod 12 relative to the base bracket 161, it is necessary to pull the two operating members 181 at the same time. According to another embodiment of the present application, as shown in FIG. 6, which is a structural schematic diagram of an adjustable mounting seat 10 according to another embodiment of the present application, the adjustable mounting seat 10 is also provided with a pull handle 19, and the pull handle 19 is connected to both operating members 181. In this way, when it is necessary to adjust the angle θ of the push rod 12 relative to the base bracket 161, the pull handle 19 is directly pulled to drive the operating member 181 to move in conjunction, thereby causing the engagement portion 1821 of the positioning member 182 to slide out of the engagement locking position, so that the pull handle 19 can be used to complete the adjustment operation with one hand.

The push rod adjustment mechanism 18 according to the present application can conveniently and effectively adjust the distance S between the push rod 12 and the tail frame 14 by conveniently and effectively adjusting the pivot angle of the push rod 12 relative to the base bracket 161, thereby adjusting the fit between the child safety seat and the car seat backrest, thereby increasing safety and reliability. The push rod adjustment mechanism 18 according to the present application has a simple structure, low cost, and simple assembly operation. It can also make the storage and installation of the child safety seat 20 more convenient.
